ROLLER-RETAINING DEVICE.

Application filed June 9, 1911.

Specification of Letters Patent.

i To all whom it may concern:

Be it known that I, ALONZO A. WARNER, a citizen of the United States,and a resident of New Britain, in the county of Hart ford, State ofConnecticut, have invented certain new and useful Improvements inRoller-Retaining Devices, of which the following is a specification.

* This invention relates to devices for preventing the accidentaldisplacement and removal of rollers which are supported at their ends inbrackets, for instance rollers 1such as are used for towels, paper andthe ike.

The object of the invention is to produce a simple, inexpensive andefiective device for the purpose described.

In the drawingsFigure 1 is a view-of a roller and its supportingbrackets embodying my invention. Fig. 2 is a sectional view through anend of the roller and one of the brackets. Fig. 3 is a side View of thebracket and roller, the knurled end of the locking pin being removed.

Referring to the drawings A denotes the brackets slotted as at B andhaving enlarged apertures C at the ends of the slots.

D is the roller.

E E are shaft pins mounted in the ends of the roller and by means ofwhich the roller is supported in the brackets. These shaft pins, or atleast one of them, is made in the following manner in accordance with myinvention. The end of the roller is recessed as at 10. A cap 11 fitsover the end of the roller and closes the recess. The cap is centrallyapertured and the shaft pin E is longitudinally movable through thisaperture being provided with an enlarged section 12 and knurled head 13.The inner end of the shaft pin is provided with a spring abutment 14;, aspring 15 being located between this abutment and the inner side of thecap. The spring normally holds the enlarged section of the pin upagainst the cap, and it is of such size that it fits the enlargedaperture 0 but is too large to slide in the slot B. It will, therefore,be

seen that when the rollers are once placed in the brackets, the springholding the enlarged section of the shaft pin in the enlarged aperture Cwill prevent the accidental removal of the roller. the roller it isnecessary to take hold of the head and draw the shaft pin out so that itis in register with the slot.

The device is simple and effective and so constructed that in theordinary use of the roller, the strain to which it is subjected does nottend to unlock it from the brackets.

I claim as my invention:

1. In a device of the character described, the combination withbrackets, one of which has a slot terminating in an enlarged aper ture,and a roller adapted to be supported by said brackets, of a shaft-pinmounted in an end of said roller, said shaft-pin being formed in twodiameters, one of which is slightly less than the width of said slot andadapted to slide therein, the diameter of the other part being greaterthan the width of said slot but adapted to fit within said onlargedaperture, said bracket and pin being adapted for relative movementlongitudinally of the pin, and means for normally holding said enlargedsection in alinement with said slot to thereby prevent disengagement ofthe roll from said bracket.

2. In a device of the character described a pair of brackets, a rolleradapted to be supported thereby, one of said brackets having a slotterminating in an enlarged aperture, a shaft pin mounted in an end ofsaid roller, and adapted to slide in said slot and having a sectionlarger than said slot but adapted to fit in said aperture, means fornormally holding said shaft pin in position with its enlarged section insaid aperture, said pin being movable longitudinally against saidholding means to disengage its enlarged section from said aperture.
